Series circuts and parallel circuts?
More devices in series means more resistance and by Ohm's law a decrease in current. Devices in a parallel circuit are like their own little circuit demanding enough current to run, and the more of them you have the greater the current flow is in the entire circuit. It can get dangerous. It's like a power strip with 6 or 7 sockets in parallel. It's easy to over amp that circuit. Thank God for circuit breakers. I think she missed the mark near the end of the first answer. Bulbs in series will not have the same current flow. Each bulb has a lot of resistance and reduces the current. They all experience the same voltage which is not even current flow.
Were is the circuit breaker on a 1971 lincoln mark III? My power windows, radio, air, and heat is not working?
There is no circuit breaker. Check your fuse box and verify that all fuses are good, then proceed with more testing. You'll need a service manual for a wiring diagram to tell you which fuses protect which circuits or you'll have to trace them down manually.
How should I study 'Circuit theory or Network Analysis' paper in engineering?
Hii friend...During btech my weakest and scariest subject was networks...I was not able to understand why we are taking current in clockwise direction and not in anticlockwise direction When we apply kvl why we take negative or positive sign...And i donot even knew that how to know whether the resistors are in pareallel or series...When i startef asking my techers they made me more confuse..I cleared that exam with very very low marks...Now i am going to give gate exam and my strongest subject is network...This happened like this...I took tutions for the network..Your concepts clarity also depends on your teacher...I found that teachers in college were themselves not clear about the concepts..They told me that resistors are said to be parallel if current division occurs there...But this is not the only reason..I took tution from one of the best teacher of my state and he made my concepts so clear ..And also i did a lot of practice . i solved 2 books of networks. What i am trying to say look out for a good teacher first and try ti learn from him....I hope i am able to answer
How can I get good marks in electric circuit theory?
If you want to get good marks in any subject then there are two ways to do that1)Study the concerned subject in proper way from recommended books, in case of circuit theory you can refercircuit theory by Abhijit Chakraborty orNetwork Analysis by HaytCircuit theory by VanValkenburg (best one)2)This is the easy way : just solve last ten year question bank of your university or exam you want to appear.I will definitely recommend you the first way because you need a proper knowledge in circuit Theory to understand other subject of electrical engineering (like electrical machine, power system, analog electronic, power electronics)Rest depends upon your Choice.
How do I get 30+ marks in physics 12th CBSE?
I guess you wish to pass the physics paper.If so i would like to give the same advice i gave it to some of my friends when we were in class 12.Read/Cram atleast among these chapters:1.Electromagnetic waves(EMW)2.Alternating current portion(Just A.C. portion say for time constraint.)3.Wave optics(Cram the Huygen's principle,wavelets etc.)4.Learn and practice numericals based on Atomic physics and nuclear physics(There are just a few formulas ,practice some questions of each pattern).5.You can practice Current electricity portion(Don't practice lots of resistance calculation question.Cover all the definitions and their formulas only.)6.For electronics portion,you should know semiconductors-their types,PN junction and effect on it by various factors,Don't forget to cram the working of pnp and npn transistor and in which region,the transistor operates as switch or amplifier.i guess this would do good.Further if you wish to score more-1.Cram all the formulas(i guess some 5-6 universal cases of dipoles-axis & equitorial,etc.) of electric potential and electric field intensity.2.Cram the generalized formula for potenial energy of n-charges system.That's what you will need for P.E. problems).But they are very rarely asked.3.You can understand the physical phenomena like rainbow,scattering of light in optics unit.p.s.-If you still have got time,Practice mirror portion of optics & read,understand the HOTS of physics.I guess it will surely help you.All the very best!
Why do you need a closed circuit to have current flow in a battery?
A battery produces electrical pressure (voltage) at its terminals, similar to water pressure in a tank. Electricity which is the flow of electrons (current) would pass from one terminal to the other without a circuit except that air (or a vacuum) has a very high resistance to electron flow. By providing a closed circuit (wire and light bulb, etc.) between the terminals there is a path for electrons to flow from one terminal to the other, similar to water flowing in a pipe under pressure. Adding two or more batteries in series with polarity in the same direction adds their electrical pressure (voltage) without providing a path of least resistance for electron flow to occur.
Basic electric circuit question? please explain how you get the answer.?
So if you imagine your Current vs. Time graph, ramping up, flat, then ramping down, the charge Q is the area under the graph, since 1 Coulomb = 1 amp.second So you've got a triangle (A = 1/2 height x base) at each end and a rectangle in the middle, and a rectangle under the triangle at the end . Q = (0.5*2*3) + (2*6) + (0.5*(2–1.5)*8) + (1.5*8) = 3 + 12 + 2 + 12 Coulomb = 29 C
What are the key subjects for gate ECE to score more marks?
The Key subjects of EC in GATE are—MathsAptitudeNetwork theory,Analog CircuitsCommunication systemSignal and SystemGATE is a technical exam ,all the subjects are very important for success in GATE exam.You should cover all the topics mentioned in the gate syllabus if you want good rank.All the best..
